An infusion of twenty-first century skills into American public education necessitates a plan for research and development to further such reform. While the nation agrees that students must obtain critical thinking, problem-solving, and communication skills to succeed in the current global marketplace, this chapter puts forth a long-term, proactive agenda to invest in targeted research to propel and sustain this shift in education. The authors examine the impact such an R&D agenda would have on pedagogy and assessment and the implications for institutions of higher education. As the United States struggles to maintain dominance in the international economy, it faces a great challenge in keeping up with European and Asian competitors' strategies for preparing youth for the global marketplace. The authors hope the global reality will help contextualize the debate around American education--the current trend toward basics and accountability needs to be broadened. Building on frameworks created by the Partnership for 21st Century Skills, this chapter proposes questions to guide research around teaching, professional development, and assessment significant to twenty-first century skills. Knowing that educational change depends on providing teachers with the tools, support, and training to make fundamental changes in their practice, the authors argue for extensive research around best practices. In addition, if assessments are created to measure the desired outcomes, such measuring tools can drive reform. Furthermore, large-scale changes in teacher preparation programs must take place to allow teachers to adequately employ twenty-first century teaching and assessment strategies.  相似文献

The caring dilemma, first described by Reverby in 1987, denotes the tension caused by being obliged to provide care without the right to determine how that care is to be provided. Such a dilemma is salient in the practice of midwifery based on a continuity of care model that has recently emerged or been implemented in various jurisdictions. Briefly, this model involves the provision of care by a single midwife or pair of midwives to a woman throughout her pregnancy, birth and post-natal period. Continuity of care necessitates that midwives be on call for significant lengths of time to ensure attendance at the woman's birth. It is the on-call nature of this form of midwifery work that most significantly poses a caring dilemma for midwives. In this paper, we trace both the structural and experiential aspects of the caring dilemma through an examination of midwifery in the Canadian province of Ontario. Our analysis reveals that despite being a salient feature of midwifery practice, some work structures can be created to mediate the caring dilemma experienced by midwives.

Le dilemme de la prise en charge, que Reverby a évoqué la première fois en 1987, dénote la tension que cause le fait d’être tenu d'offrir une prise en charge sans avoir le droit d’établir de quelle manière l'offrir. L'exemple des sages-femmes, dont la pratique repose sur un type de soin continu qui est récemment apparu ou qu'on vient de mettre sur pied dans diverses administrations, illustre très clairement ce dilemme. Pour résumer, ce modèle veut qu'une femme enceinte soit prise en charge pendant sa grossesse, à son accouchement et durant sa période postnatale par une ou deux sages-femmes. La continuité de la prise en charge oblige les sages-femmes à être sur appel durant des périodes prolongées pour que la femme qui accouche bénéficie de leur présence. Pour les sages-femmes, c'est la nature même de leur travail effectué sur appel qui engendre, de façon cruciale, le dilemme de la prise en charge. Dans cet article, nous abordons les aspects structurels et expérimentaux que représente le dilemme de la prise en charge par le biais d'une étude sur la pratique du métier de sage-femme dans la province canadienne de l'Ontario. Notre analyse révèle que, si le dilemme de la prise en charge est inhérent à la profession de sage-femme, il n'empêche que des structures professionnelles peuvent être mises en place pour en atténuer les aspects négatifs.  相似文献

The Dual Process Model of Coping with Bereavement (DPM; Stroebe & Schut, 1999) is described in this article. The rationale is given as to why this model was deemed necessary and how it was designed to overcome limitations of earlier models of adaptive coping with loss. Although building on earlier theoretical formulations, it contrasts with other models along a number of dimensions which are outlined. In addition to describing the basic parameters of the DPM, theoretical and empirical developments that have taken place since the original publication of the model are summarized. Guidelines for future research are given focusing on principles that should be followed to put the model to stringent empirical test.  相似文献

A graphical procedure for the display of treatment means that enables one to determine the statistical significance of the observed differences is presented. It is shown that the widely used least significant difference and honestly significant difference statistics can be used to construct plots in which any two means whose uncertainty intervals do not overlap are significantly different at the assigned probability level. It is argued that these plots, because of their straightforward decision rules, are more effective than those that show the observed means with standard errors or confidence limits. Several examples of the proposed displays are included to illustrate the procedure.  相似文献

Abstract

IFLA Library Reference Model (IFLA LRM) represents the consolidation of Functional Requirements for Bibliographic Records (FRBR) and the two other conceptual models of the Functional Requirements (FR) family, the Functional Requirements for Authority Data (FRAD) and the Functional Requirements for Subject Authority Data (FRSAD). IFLA LRM includes a specific section (5.8) devoted to serials. The RDA Steering Committee adopted IFLA LRM as the conceptual model for the development of RDA in November 2016. The 3R (RDA Toolkit Restructure and Redesign) Project’s purpose is partly to make RDA compatible with the IFLA LRM. A beta version of the English-language content of the RDA Toolkit, which incorporates the IFLA LRM, was released in June 2018. This column explores, in lay terms, serials in relation to the IFLA LRM and the RDA Toolkit Restructure and Redesign (3R) Project. The beta version of the restructured and redesigned RDA Toolkit introduces several new concepts relating to serials.  相似文献

In the presence of rare disasters, risk perceptions may not always align with actual risks. These perceptions can nevertheless influence an individual's willingness to mitigate risks through activities such as purchasing flood insurance. In a survey of Maryland floodplain residents, we find that stated risk perceptions predict voluntary flood insurance take‐up, while perceptions themselves varied widely among surveyed residents, owing in large part to differences in past flood experience. We use a formal test for overoptimism in risk perceptions and find that, on aggregate, floodplain residents are overly optimistic about flood risks.  相似文献

Covenant marriage may be difficult to understand as a gender issue. However, marriage and divorce are closely linked to workforce participation and child rearing. This piece looks at new proposals for choices in divorce regime from legal, economic, and social perspectives, concluding that the option of contracting a more permanent form of marriage increases the possibilities for women and signals societal interest in promoting more stable families. The article favorably compares Louisiana covenant marriage legislation to other states' suggestions for returns to fault-only regimes, and pays some attention to the role one state's marriage and divorce laws play in the federal system.  相似文献

Leaf litter, by modifying microenvironmental conditions, can alter plant population distributions and is considered to be a major force in structuring many plant communities. Comparative studies of urban, suburban, and rural forests in the New York City (NYC) metropolitan area have identified numerous biotic and abiotic differences among these forests, including several involved in leaf litter decomposition. These differences in decomposition among the forests could result in differences in litter quantity on the forest floor and hence microenvironmental conditions and safe sites for germination of different plant species. We conducted a survey of forest floor leaf litter quantity in forests located along an urban-to-rural land-use gradient originating in urban NYC and extending to rural Connecticut. Mean litter depth, mass, and density increased significantly with increased distance of the forest from NYC.We also surveyed woody seedlings and compared the litter depth in which they naturally occurred to the mean litter depth of the surrounding forest. Seedlings of small-seeded species were much more likely to be located in litter shallower than mean forest litter depth than were seedlings of large-seeded species. Taken together, these results suggest that environmental changes associated with urbanization may have profound effects on long-term patterns of forest regeneration.  相似文献

Topics in Microbial Risk Assessment: Dynamic Flow Tree Process   总被引:5,自引:0,他引:5  
Microbial risk assessment is emerging as a new discipline in risk assessment. A systematic approach to microbial risk assessment is presented that employs data analysis for developing parsimonious models and accounts formally for the variability and uncertainty of model inputs using analysis of variance and Monte Carlo simulation. The purpose of the paper is to raise and examine issues in conducting microbial risk assessments. The enteric pathogen Escherichia coli O157:H7 was selected as an example for this study due to its significance to public health. The framework for our work is consistent with the risk assessment components described by the National Research Council in 1983 (hazard identification; exposure assessment; dose-response assessment; and risk characterization). Exposure assessment focuses on hamburgers, cooked a range of temperatures from rare to well done, the latter typical for fast food restaurants. Features of the model include predictive microbiology components that account for random stochastic growth and death of organisms in hamburger. For dose-response modeling, Shigella data from human feeding studies were used as a surrogate for E. coli O157:H7. Risks were calculated using a threshold model and an alternative nonthreshold model. The 95% probability intervals for risk of illness for product cooked to a given internal temperature spanned five orders of magnitude for these models. The existence of even a small threshold has a dramatic impact on the estimated risk.  相似文献
